"Jed went above and beyond installing my new ceiling fan. He had to get some supplies and worked in my hot attic and made sure that it was wired correctly. This involved cutting through the old inside wood 2nd layer roof to get to the hidden electrical wires where he put a junction box and new wiring for the fan and light kit. He stayed longer than necessary and completed the job that night after working all day. He is a consummate professional and I will hire him again. through"

"I own a business and had a company come out to fix our air conditioner. They came out 4 times, charged for all those time and the unit still was not working properly. I then decided to try someone else, so I called Thermotech on the referral of a friend. They came out, diagnosed the problem within 10 minutes (it was an old crumbling circuit board), showed me that bad part, ordered it and had it fixed in less than 24 hours. We have not had a single problem since! I was so happy with their service that I ended up using them for my home HVAC system.. I even referred them to a family member and they did a home install of a brand new HVAC system and they were very happy with the price, install, workmanship & fair pricing. Thermotech has found a customer for life with me. I have had so many bad experiences over the years with other companies telling & thermotech has been a game changer."

Heating and Air Conditioning questions, answered by experts

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Signs that your air conditioner capacitor is bad or failing include a range of symptoms. The AC unit may not turn on at all, or it might struggle to start before shutting down randomly or in the middle of a cooling cycle. You might hear a humming or banging noise when it attempts to start, or the compressor might hum without the unit actually running. Other indicators include a smell or smoke coming from the unit, the blower circulating room-temperature air instead of cold air, and an unexpected increase in your energy bills.

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.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.
