"I've been hiring Tony from Cold Air Mechanical for about 10 years. First for my apartment management business when my on staff techs couldn't figure out the problem and then at my home. He's always very pleasant to work with and very knowledgeable. Where I've had other HVAC techs try to sell me unnecessary equipment for outrageous prices (thank you Private Equity), he's actually identified the problem and usually has the part in his van at a fair price. While I'm not HVAC certified, I know my way around and I'd definitely recommend Tony."

"Theo, the owner is great as an HVAC pro. We asked him to come out for the tune-up going into the summer season. He checked, very thoroughly, both our units. One was good to go, but the other one needed 6lbs of freon. Theo explained everything and showed us everything that he checked. He even tried to work with our home warranty company to see if they would cover the cost of repair/replacement, but they would not. Theo gave us our options and we asked him for his honest recommendation. He said a new unit. Ours is nearly 20 years old and has been repaired several times recently. We went with a new unit and he was able to install it within two days of us talking. He made sure the installation was smooth and with minimal interruptions. His thoroughness have us feeling better about our decision and trust in his judgement and professionalism. Very good HVAC pro and a good guy to do business with during these times."

"The tech was very knowledgeable and skillful. He had to install the new blower fan into the existing fan housing, but he took the existing blower assembly (fan, motor, electrical, and housing) out to his truck in inclement weather to do the work. I offered up my garage, but he said that he would be fine out in his truck. From start to finish it could not have been more than 40 minutes. The blower unit runs and sounds like a brand-new install. Very quiet. Prior to the repair the blower sounded like a freight train passing through the house. Very happy and the cost was reasonable."

Heating and Air Conditioning FAQs, answered by experts

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

If both your furnace and AC unit are more than a decade old, it may be a good idea to replace both of them. However, your furnace can last up to three decades, and your air conditioner can typically last up to 15 years, so consulting with a pro before deciding to replace both of them is best. If it’s before that time limit for each, you can fix many problems with repairs or just replace one.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.
