"Eddie and Lennon are pros. They were the first company to call back after leaving a message I need help. I hired them to check the air conditioning and discovered it had a big leak. After looking and talking, the system including the furnace needed to be replaced. I decided to change the system after negotiating a price and they started to take out the old air conditioner and heater that afternoon and come back the next morning to install the new system. I asked Eddie if he could install a Nest Learning Thermostat I had purchased and he said no problem. They did cleaned up like they were never there. The new system works perfectly and with less noise too. Champion Aire Heating and Air Conditioning was the right choice to hire. Very satisfied customer and would hire them again for maintenance when needed."

"Responded to my call expeditiously with their technician, Jayce, arriving within an hour. He troubleshot our AC and quickly identified the problem as a failed fan assemble. All the parts he required were in his van and repairs were made on site. Throughly tested our AC and verified repairs were successful. Thank you Jayce."

"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"Daniel from AC Doctor Heating and Air Conditioning provided outstanding service from start to finish. He quickly diagnosed the issue with my unit and was able to get everything back up and running the very same day, which I truly appreciated. Daniel was professional, knowledgeable, and took the time to clearly explain what the problem was and how he planned to fix it. His responsiveness, attention to detail, and commitment to customer service really stood out. You can tell he takes pride in his work and wants to make sure the job is done right the first time. I highly recommend AC Doctor Heating and Air Conditioning to anyone looking for fast, honest, and high-quality HVAC service. Excellent experience overall!"

"They came out and found our panel wasn't big enough to carry all the things we had. A new panel was put on and the A/C was serviced. We had another condenser put in as well. The ducts were also checked and found to have a broken one in the attic. they were very nice and did the work right away."

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

Air Conditioning questions, answered by experts

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

If possible, avoid placing furniture in front of a return air vent. A blocked air vent can cause your HVAC system to use more energy, which in turn can lower the life span of your unit and raise your energy bill. Furniture can also trap hot or cold air, damaging your furniture or appliances. 

Professional duct installers suggest leaving between six and 12 inches of space in front of an air return vent. If you must place furniture in front of a return air vent, try to aim for putting furniture over a floor vent instead of in front of a wall vent, and avoid draping curtains over any vent system.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.

The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don’t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
