"Damien came out and checked my unit and told me exactly what was wrong. The unit had a leak. He fixed the problem and checked back on several occasions to make sure that the unit was running properly ( never had a company to do a follow up like he did). Very impressed. He will be the only person that I will call for any future HVAC needs. Very professional and will highly recommend."

"Scott was great and his helper Ray was very thorough. I had them come out for a musty smell in my HVAC ducts. They cleaned all the vents and returns, then fogged them after they were finished. He even offered to come back out and fog again if needed and I did end up calling them back out for a second fog because of a faint smell in one of the rooms. He came out free of charge the second time. Very good service and I would recommend! The smell is gone!"

"If you are having HVAC issues I would definitely recommend going with this company! We had a really great experience. We contacted them at around 8pm about an issue with our ac not cooling the house down and within 30mins charles called back and we were able to set a date for the next day to have our A/C looked at. Charles arrived exactly within the time he told us he would. He did a great job! Our A/C is working great and we couldnâ t be happier! They put customers first here and went above our expectations. Best company we have used by far! Thank you!"

"Preferred Home Services installed a brand new Split unit HVAC system including ductwork. They were fast efficient extremely professional and very knowledgeable. They explained everything they were doing before during and after they did it. Most importantly they cleaned up afterwards, to the point you couldn't even tell they were here. I also had them install a brand new water heater while they were at it. Everything is brand new and up to code I am very pleased. Thank you Angie's List for the referral. I will consider Preferred Home Services as my go-to from now on for my HVAC and water heater."

Heating and Air Conditioning FAQs, answered by experts

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.
