"We were extremely pleased with the service provided to us by Bob's Air Repair and their technician Luke T. The heating in our HVAC system was failing to launch when turned on, although it made noises of an attempt to do so. From the time we placed the service request to Luke's arrival everything was handled in a efficient & professional manner."

"I purchased a new, fairly expensive thermostat. I needed a certified HVAC person to install it in order to preserve the 10-year warranty. I utilized Angi to find someone local to do that. I was soon contacted by Nick. We discussed a priced and he showed up the next day. Nick was extremely cordial. He was very easy to communicate with and he is generally just a very nice person. Nick was knowledgeable and completed the job in short order. He provided me with a receipt and then went on his way. I am very happy with his work and I think that if he does some work for you, then you will have a similar outcome."

"We pay $14/mo. and they automatically come out twice a year.  They come in January and check your heater and July and check your A/C.  Then you get a discount on any service needed.  It's great, they always are good. I think they're kind of expensive but, well they're probably no more expensive than others.  It always cost a lot when you have to have repairs done.  They are always very responsive when we call. They're always here within the time frame that they give us.  Only one time did they call and say they would be later."

"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"

Heating and Air Conditioning questions, answered by experts

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.

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Signs that your A/C system needs professional service include increased energy bills, uneven or poor cooling, loud or unusual noises, and frequent cycling.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.
