"I used their website feature to request a tech for residential A/C repair for the following day. But I received a phone call from Cytech a couple of hours later asking if I wanted service earlier as they had a tech available at that time, which worked out even better for me. The service call and repair was completed in 45 minutes after tech arrived in a efficient and professional manner. Tech even went above and beyond the repair and fixed up a couple of minor issues without charging me anything additional. I'll will be calling them again in the future should I need HVAC services!"

"Great thermostat installation service. The technician was punctual, professional, and made the entire process easy to understand. The new thermostat works perfectly, and they took the time to ensure everything was properly configured before leaving. Excellent customer service and quality work. Highly recommend!"

Heating and Air Conditioning FAQs, answered by experts

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

There are two main reasons your furnace and AC are turning on at the same time. The first could be that you’re confusing the furnace with the blower. The blower is located in the furnace and will turn on to distribute cool air from the air conditioner through the ductwork in the home. This is normal. If the actual furnace is turning on at the same time as the AC and hot and cool air are coming into the home, it could be a result of incorrect writing to a new thermostat or new systems.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.
