Lovinaire Heating and Cooling serves homeowners, landlords, property managers, and businesses across Claremont and the surrounding Los Angeles County area. We handle the full range of heating and cooling work, from a same-day repair call to a complete system replacement, and we treat every job the same way: show up ready, do the work right, and leave the space clean. Whether you need an AC diagnosed on a hot afternoon or a new heat pump system installed from scratch, we are the local HVAC company to call. Arrives fast. Repairs it right. Priced fair. Call (909) 929-7895 to get started.
We've handled everything from a quick tune-up to a full system swap, and the work is always the same: figure out what the system needs and get it done without drama. We service and install central air conditioners, furnaces, heat pumps, ductless mini-splits, thermostats and smart controls, ductwork, and whole-house air filtration systems. Residential customers, landlords managing rental properties, and commercial clients all get the same straightforward service. We are a local HVAC company homeowners rely on, and that reputation is built one job at a time. Call (909) 929-7895 to schedule a visit or get a quote on any heating or cooling work.
When the AC stops working, you need answers quickly. We diagnose and repair the most common air conditioner problems: system not turning on, blowing warm or room-temperature air, uneven cooling from room to room, refrigerant leak diagnosis and repair, condenser and compressor issues, and evaporator coil cleaning. Same-day availability is open for urgent calls, so you are not waiting days in the heat for a technician to show up. All diagnostic and repair work is performed by qualified HVAC technicians who know what to look for and how to fix it correctly. Your system is in good hands with us.
When a repair no longer makes financial sense, a full AC replacement is the right move. We handle central air conditioner replacement from start to finish. On the day of installation, our technicians remove the old equipment, install the new unit, verify refrigerant charge, test airflow and controls, and confirm the system is running properly before we leave. We help you choose equipment that fits your home's size and your comfort goals, and we keep energy-efficiency considerations in plain view so you understand what you are getting. Call (909) 929-7895 to get a quote on AC replacement or new installation.
Every home's heating and cooling setup tells a different story, and no-heat situations are never one-size-fits-all. We diagnose furnaces that won't fire, heating systems blowing cold air, and gas furnace failures of all kinds. Same-day and emergency furnace repair appointments are available when the heat goes out and you cannot wait. We give you straight answers about what is wrong, what the repair involves, and what it will cost before any work begins. We'll service the system and clean up after.
Sometimes a furnace repair makes sense. Sometimes the age of the equipment, the cost of the part, or the pattern of breakdowns points clearly toward replacement. We walk you through that decision honestly. A replacement visit involves removing the old unit, installing and connecting the new furnace, testing ignition and heat output, and confirming that airflow through the ductwork is balanced. Call (909) 929-7895 for a quote on furnace replacement and we will tell you exactly what the job involves.
A heat pump that won't heat, won't cool, or won't turn on at all is a system that needs attention today. We diagnose and repair heat pump problems across all makes and models, and we handle full heat pump replacement when the equipment has reached the end of its useful life. Ductless mini-split systems fall under the same umbrella. If your home runs on a mini-split or you are considering one, we install, service, and repair those systems as well. We give you straight answers about your furnace, AC, and ductwork, no surprises, and that same standard applies to every heat pump call we take. We find the fault. We make the repair. We restore the comfort. Call and we'll handle the furnace, the AC, and the ductwork.
Leaking or poorly sealed ductwork wastes conditioned air before it ever reaches the rooms you are trying to heat or cool. If certain rooms in your home are always too hot or too cold, or your energy bills seem out of step with your usage, the ductwork is often the first place to look. We inspect, seal, and replace ductwork to restore proper airflow and even temperatures throughout the house. The comfort improvement is usually immediate, and the efficiency gain shows up on the next utility bill.
A thermostat that reads the wrong temperature, fails to hold a schedule, or stops communicating with the system causes real comfort problems. We replace faulty thermostats and install programmable and smart thermostat models that give you better control over your heating and cooling. A typical installation visit involves removing the old unit, wiring and mounting the new one, confirming it communicates correctly with your HVAC equipment, and walking you through the settings before we leave.
A home that heats and cools right is a comfortable home, but air quality is part of that picture too. We install whole-house air filtration systems, UV air purifiers, and high-efficiency air scrubbers that work with your existing HVAC equipment. We also handle HVAC filter upgrades and replacement. For Claremont residents, indoor air quality is not an abstract concern. Inland Southern California sees some of the region's worst air during wildfire events, and the right filtration system makes a real difference when smoke moves through the area. We show up ready to go to work.
Inland Southern California has its own set of HVAC demands. Claremont sits in a zone where summer heat can be intense, wildfire smoke rolls through seasonally, and the broader Los Angeles County region is actively pushing toward electric-first heating and cooling systems. The three services below reflect what actually comes up most often for homes and buildings in this area.
Many older Claremont homes were built during an era when air conditioning was not standard in this part of California. The mild coastal influence historically kept adoption low, but recent record heat events have changed that calculation fast. For homes without existing ductwork, a ductless mini-split system is the practical answer. We assess the layout of your home, recommend the right configuration of indoor and outdoor units, and handle the full installation. There is no need to tear into walls or run new duct runs. The system goes in cleanly, and you have cooling where you need it.
When wildfire smoke moves into the Los Angeles County area, the air inside a home can be as problematic as the air outside if the HVAC system is not equipped to handle it. We install high-efficiency air filtration systems capable of MERV-13 ratings and above, whole-house air scrubbers, and media filter upgrades that capture fine smoke particles before they circulate through your living space. If your current system runs a standard filter, an upgrade to a MERV-13-capable setup is a straightforward improvement that pays off every fire season.
Southern California homeowners are replacing gas-forced-air systems with heat pump systems at a growing rate, driven by both comfort goals and the region's broader push toward electric-first buildings. A heat pump handles both heating and cooling from a single system, which simplifies the equipment in your home and removes the dependency on gas for space heating. We install heat pump systems for homeowners upgrading from a furnace, size the equipment to the home, and handle the full installation of the indoor and outdoor units. The result is a system that heats in winter, cools in summer, and does both efficiently.
For homeowners and property managers who want it done right, a seasonal tune-up is the simplest way to stay ahead of breakdowns. A spring tune-up prepares the AC for summer demand. A fall tune-up gets the heating system ready before the first cold stretch. During each visit, we inspect the equipment, clean components, check refrigerant levels, test controls and safety switches, and flag anything that looks like it could become a problem. This is the kind of HVAC work neighbors pass along by word of mouth, because it keeps systems running reliably and catches small issues before they turn into emergency calls. We'll service the system and clean up after.
A system that goes down in the middle of a heat wave or a cold night is an emergency, and we treat it like one. We take same-day and after-hours calls for no-heat and no-cool situations, system failures, and any HVAC problem that cannot wait for a regular appointment. Both residential customers and commercial properties are covered. Arrives fast. Repairs it right. Priced fair. Call (909) 929-7895 any time you need emergency HVAC service in Claremont or the surrounding area.
Property managers and business owners have different demands than a single-family homeowner, and we understand that. We service and repair commercial air conditioning and heating systems, handle commercial HVAC installation and replacement, and work on office buildings, retail spaces, and multi-tenant properties across the area. Work is performed by qualified HVAC technicians, and pricing is straightforward before any work begins. If your building's system is down or underperforming, call (909) 929-7895 and we will get a technician out to assess it.
We started this business in 2022 with a straightforward goal: provide honest, reliable heating and cooling service to the people and businesses in Claremont and Los Angeles County. Four years in, that has not changed. Every call we take, every system we service, and every installation we complete reflects the same standard we set from day one.
You're talking to someone who knows the area and the systems in it. Claremont has a mix of older homes, newer construction, and commercial properties, and we have worked on all of it. We know what the local climate demands and what the common equipment issues look like in this part of Southern California.
We serve residential customers, landlords, property managers, and businesses. Whether it is a single-family home in need of a first-time AC installation or a commercial property with a system that needs replacing, we bring the same care and the same honesty to the job.
We serve Claremont and the surrounding communities throughout the Pomona Valley and San Gabriel Valley, including Upland, Montclair, Ontario, Pomona, La Verne, San Dimas, Rancho Cucamonga, and Chino Hills. If you are nearby and not sure whether we cover your address, call us at (909) 929-7895 and we will confirm quickly.
Yes. When you call (909) 929-7895, you reach someone who knows the area and the systems in it. We are locally owned and personally accountable, and the person who answers your call is part of the same operation that sends the technician to your door.
We are available every day from 5:00 AM to 9:00 PM, including Saturdays and Sundays. If your system goes down over the weekend, call (909) 929-7895 and we will work to get a technician out the same day when slots are available.
For urgent situations, including no-cool calls during a Claremont heat event or a no-heat situation on a cold night, we dispatch same-day when our schedule allows. Call as early as possible so we can fit you into the day's routing.
Call us at (909) 929-7895. We will ask a few questions about the system and the symptoms, confirm your address and availability, and schedule a technician visit. Having your equipment make, model, and a brief description of the problem ready will help us prepare for the call.
Check that the thermostat is set correctly and that the circuit breaker for the air handler or furnace has not tripped. Also confirm the system switch near the air handler is in the on position. If none of those are the issue, call us at (909) 929-7895 and we will send a qualified HVAC technician to diagnose it.
Warm air coming from the vents when cooling is set, weak or uneven airflow across rooms, short cycling where the system runs briefly and shuts off repeatedly, and unusual sounds like grinding or banging are all signs the system needs attention soon. Burning smells or the smell of something overheating are reasons to shut the system off and call immediately.
We provide a clear quote before any work begins, and we communicate with you before proceeding if something changes during the job. We do not believe in invoices that look different from the estimate you agreed to.
We look at the age of the equipment, the cost of the repair relative to the system's remaining useful life, and the pattern of breakdowns. If repair makes sense, we say so. If the numbers point toward replacement, we explain that plainly and let you make the decision with full information.
Yes. We work with property managers, landlords, and business owners across the Claremont area on commercial HVAC repair, maintenance, and installation. Office buildings, retail spaces, and multi-unit residential properties are all part of what we handle.
We serve a defined area across the Pomona Valley and surrounding communities, and our standard pricing applies within that area. If you are on the edge of our coverage zone, call us at (909) 929-7895 and we will let you know what to expect before we schedule anything.
We handle AC repair and installation, furnace and heating service, heat pump repair and electrification, ductless mini-split installation, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, seasonal maintenance, and emergency HVAC service across Claremont and the surrounding Los Angeles County area. Pick the date. We do the work. We clean up after. Call (909) 929-7895 to schedule service or get a quote. We are ready when you are.
We handle the full range of heating and cooling work across Claremont and the surrounding Los Angeles County area, from a same-day repair call to a complete system replacement. Whether you are dealing with an AC that stopped cooling, a furnace that will not fire, or a home that has never had air conditioning at all, we bring the same straightforward approach to every job: show up ready, do the work right, and leave the space clean. The table below covers what we offer, who each service fits best, and a few practical notes to help you figure out where to start.
| System Service | What's Included | Best For | Good to Know |
|---|---|---|---|
| Heating and Furnace Repair | no-heat diagnosis, gas furnace fault repair, ignition and heat-output testing, emergency same-day appointments | any home where the heater is blowing cold air or will not start at all | Claremont winters are mild but real; a furnace that fails on a cold night qualifies as an emergency call. |
| Emergency HVAC Service | same-day and after-hours dispatch, no-heat and no-cool calls, system-down response, residential and commercial coverage | any situation where the system is completely down and waiting for a regular appointment is not an option | We take emergency calls every day; call as early as possible so we can fit you into same-day routing. |
| Ductwork Repair and Sealing | duct inspection and leak detection, sealing and repair, duct section replacement, airflow balancing | homes with rooms that are always too hot or too cold, or energy bills that seem higher than they should be | Leaky ductwork can waste a significant share of conditioned air before it ever reaches the living space. |
| Thermostat and Smart-Control Installation | faulty thermostat replacement, programmable and smart thermostat install, system communication verification, settings walkthrough with the homeowner | anyone whose thermostat reads wrong temperatures, drops schedules, or has stopped talking to the HVAC equipment | A smart thermostat upgrade is one of the lowest-cost ways to improve day-to-day comfort and energy use. |
| Seasonal Maintenance and Tune-Ups | equipment inspection and cleaning, refrigerant level check, controls and safety-switch testing, early fault identification | homeowners and property managers who want to stay ahead of breakdowns rather than react to them | A spring tune-up preps the AC for summer heat; a fall tune-up gets the heating system ready before the first cold stretch. |
| First-Time AC and Ductless Cooling Installation | home layout assessment, mini-split system sizing, indoor and outdoor unit installation, no ductwork required | older Claremont homes that were built without central air and do not have existing ductwork | Recent heat events have accelerated demand for first-time cooling in homes that historically did not need it. |

How do I know whether to repair my AC or replace it entirely?
We look at a few things together: the age of the equipment, the cost of the repair relative to what a replacement would run, and whether the system has been breaking down repeatedly. A younger system with a single fault is usually worth repairing. A system that is ten or more years old, needs an expensive part, and has already had several repair calls in recent seasons is often a better candidate for replacement. We walk you through that comparison honestly and let you make the decision with full information.
Why would my system stop heating or cooling even though it is running?
A system that is running but not conditioning the air usually has one of a few causes: a refrigerant leak, a dirty or blocked coil, an airflow restriction from a clogged filter, a failing compressor, or a controls issue where the system thinks it is doing the right thing but is not. A qualified HVAC technician can diagnose the specific cause quickly. We give you a clear explanation of what we found before any repair work begins.
How often should I schedule a tune-up or maintenance visit?
Twice a year is the standard: once in spring before the cooling season and once in fall before the heating season. Each visit covers inspection, cleaning, refrigerant check, and controls testing. Staying on that schedule helps catch small problems before they turn into emergency calls, which is usually a better outcome for both the equipment and the budget.
Transparent Pricing Before Any Work Begins
We provide a clear quote before we start, and we communicate with you before proceeding if anything changes during the job. The invoice should not look different from the estimate you agreed to.
What do strange noises from my HVAC unit usually mean?
It depends on the sound. Grinding or metal-on-metal noise often points to a bearing or blower motor issue. Banging can mean a loose component inside the unit. A high-pitched squealing sometimes indicates a belt or motor problem. Clicking at startup is normal; clicking that continues through a cycle is not. Any sound that is new or getting louder is worth a technician visit before it turns into a bigger failure.
Can a dirty filter or coil actually hurt system performance?
Yes, significantly. A clogged filter restricts the airflow the system depends on, which forces the equipment to work harder and can cause the evaporator coil to freeze. A dirty coil loses its ability to transfer heat efficiently, which means the system runs longer to do less. Both problems show up as higher energy use, weaker cooling or heating, and more wear on the equipment over time. Replacing the filter regularly and scheduling annual coil cleaning are two of the simplest ways to protect the system.
Why is one room in my home always hotter or colder than the rest?
Uneven temperatures across rooms usually come from one of three places: a ductwork problem such as a leak or a disconnected run, an airflow imbalance in the system, or an equipment issue like a failing blower motor. Older homes sometimes have duct layouts that were not designed for the current system. We inspect the ductwork and the equipment to find the actual cause rather than guessing.
Work Performed by Qualified HVAC Technicians
Every repair, installation, and maintenance visit is handled by qualified HVAC technicians who know the equipment and know what to look for. We do not cut corners on the work or on how we communicate with you about it.
What does a thermostat or smart-control upgrade actually involve?
A typical thermostat installation takes less than an hour. We remove the old unit, check the wiring at the wall, mount and wire the new thermostat, confirm it is communicating correctly with the HVAC equipment, and walk you through the settings before we leave. A smart thermostat that connects to your phone or a home system takes the same amount of time; the extra step is confirming the Wi-Fi pairing and app setup works before we go.
Do I need to be home during the service visit?
For work inside the home, yes, someone needs to be there to provide access and sign off on the work. For outdoor-only work on a condenser or heat pump unit where no interior access is needed, we can sometimes arrange access differently. Call us and we will work out the logistics based on what the job involves.
Experienced With Older and Newer Systems
Claremont has a mix of older homes, newer construction, and commercial properties, and we have worked on all of it. Whether the system is decades old or recently installed, we bring the same care to the diagnosis and the repair.
How does same-day or emergency service work?
Call us at (909) 929-7895 as early in the day as possible. We ask a few questions about the system and the symptoms, check our schedule, and dispatch a technician the same day when slots are available. No-heat and no-cool calls get priority. Both residential customers and commercial properties are covered for emergency dispatch.
How do MERV-13 filters help during wildfire smoke events?
Standard one-inch filters capture larger particles but let fine smoke particles pass through and circulate in the home. MERV-13-rated filters and above are designed to capture much smaller particles, including the fine particulate matter that makes wildfire smoke harmful indoors. We install MERV-13-capable filter housings, whole-house air scrubbers, and media filter upgrades that work with your existing HVAC equipment. For homes in the Claremont area, where smoke from regional fires can settle for days at a time, the upgrade is a practical one.
What is involved in switching from a gas furnace to a heat pump?
We size a heat pump system to the home, select the indoor and outdoor units, remove the old furnace, and install the new equipment. A heat pump handles both heating in winter and cooling in summer from a single system, which simplifies what is in the home and removes the dependency on gas for space heating. We handle the full installation and test both modes before we leave. If you have questions about whether the switch makes sense for your home, call us and we will walk through it with you.
Call (909) 929-7895 and we will help you figure out exactly what your system needs and get it scheduled.
