"We were very pleased with the service that we received from CARE! I contacted three different companies and they were the first to respond and their estimate was the cheapest. We were looking for a basic system and that is exactly what we got. We did not feel pressured to get anything more than we asked for and Andy was very helpful. Matt and Kirk, who installed our new system, were fast and efficient. We will definitely contact CARE again in the future for any HVAC needs."

"I’m so glad I went with APEX Pros. I was under the misconception that going with the bigger companies meant more money yet, I have had small business owners give extremely high estimates even without expressing the full scope of the job. I have also been taken advantage of by the smaller companies several times. With APEX Pros, the technician Romerial was extremely knowledgeable and was able to diagnose the job quickly. There were some broken support brackets from the drain pan and so everything was draining to the floor. In order to cool we had to swim basically. Floor was covered and each tech before APEX and Romerial had no clue what to do. It’s been going on for months and now I have a dry basement. The technician explained the job, showed me exactly what was going on, walked me through the full scope of the job, then estimated the time at two hours, brought a level of calm and comfort to me that I had not not even once during the hvac issue. I definitely recommend them."

Heating and Air Conditioning FAQs, answered by experts

It depends on the type of AC unit and the extent of the mold growth. For example, if you have a small amount of mold in your central air conditioner, it’s worth cleaning it to protect your HVAC system and your health. In situations like these, you can often remove the mold yourself in a couple of hours. On the other hand, if you have a portable AC unit with a severe mold problem, it makes more sense to buy a new one. On average, replacing a portable AC unit costs $100 to $500.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with. 

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.
