"Our HVAC unit wasn't working and was recently repaired by another shop.  After a couple of weeks, it stopped working again.  The other repair shop couldn't figure out what was wrong...after replacing the board and fuses.  They claimed the unit was old and we needed an electrician to fix the electrical problem.
The appointment with Duke started off poorly...he forgot about the appointment.  After calling to ask where he was, he made it over in 45 mins.  We wanted Duke to give us an estimate to replace the Heater and A/C unit.  He took measurements and drafted up an estimate to replace the HVAC, roughly $4500.  Then he asked what was wrong with the unit.  Out of curiosity, he looked at the wiring and replaced the fuse.  After, the fuse blew out a number of time, he was able to figure out a wire had melted and was causing it to blow the fuse.
So after spending $300 with another company to replace the board and having the unit still not work, Duke was able to fix it for $150 (service call).  Then told us the unit should be good for another 5-10yrs.  He may have lost out on a $4500 job replacing the unit and getting only $150 for a service call, but he's going to be our first call the next time we ever have a repair job and eventually replace the unit.  It's great to find honest, competent repair guys like Duke!!  Thanks!

"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"John did an amazing job with our HVAC system! From the moment he arrived, he was professional, knowledgeable, and took the time to explain everything clearly. His workmanship was top-notch, and he made sure everything was working perfectly before he left. It?s hard to find someone who genuinely cares about doing quality work, but John definitely does. If you?re looking for an honest, reliable HVAC contractor who takes pride in what he does, I highly recommend John. I couldn?t be happier with the service!"

"I highly recommend Aire Serv of Campbell & Saratoga to anyone in need of HVAC services. Alton helped me find the right system that works for our home within my budget. Alton was knowledgeable and truly explained the different options & HVAC available that would fit for our home. Alton answered all my questions with patience and expertise.

"Michael, the estimator, came out and got all the information. He was very professional and even talked about various different options including putting the heater in the attic. He was very knowledgeable. I chose to go with another company, but I believe that Albert Nahman Plumbing and Heating would have done a great job on the work proposed."

Heating and Air Conditioning questions, answered by experts

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

Running a window air conditioner unit costs about $0.06 to $0.88 per hour. Choosing the correct size air conditioner can help it run more efficiently.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.
