"Cal helped out tremendously. Came in was able to diagnose the issues, and able to teach me a few things as well. It’s an old firehouse that didn’t have a thermostat amongst other part that were missing which kept it from being habitable in the winter. He came in with his team and was able to fix the 3 boiler system and get a thermostat. Now it’s no longer under 50 inside the building. Definitely recommend."

"I needed an entire new house system with all duct work installed and lines and power. I had window units for air and baseboard for heat. Greg's team was great to work with. Always on time and very professional. Did a great job on the install and I love the system Can't even hear it run. They worked and listened to me on ideas I had on what I wanted to have done, and we worked well together to come to a final solution that worked, as some of the ducts was hard to install. Would use the Blair team anytime. P.S. Great price on the system"

"Ben showed up to provide estimate for services. Ben was the only person from the companies I contacted who conducted a Manual J calculation to determine my homes needs.

"I woke up Friday morning to no hot water at my home. I was given Aaron?s info later that morning from my cousin and called him around 3pm on my lunch hr. He met me at my house by 8pm THAT NIGHT to replace heating elements & thermostats in both of my water heaters. We weren?t sure this would work or if I would need to replace the units (having well water wreaks havoc on appliances over time) but he offered ?the cheaper fix? instead of just pushing new units which I appreciated. The repairs he performed got both units working properly but when we turned the water back on to the house, a leak had sprung at the main shutoff valve that had been damaged from years of exposure to the harsh well water. He immediately said ?well, looks like I?m not leaving?. He then proceeded without hesitation to replace the main valve that controls the water into my home. Had he not done that we wouldn?t have had ANY water for the night. He did awesome work and responded quickly to my immediate need!!!!!! "

Heating and Air Conditioning questions, answered by experts

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

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.
