"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Juan has helped us for over 2 years. He is always very prompt, reliable, professional and best of all, he knows his stuff! He has always come same-day for our both heating and air emergencies. We board little and big critters, cats, dogs, lizards, bunnies, birds, you name it and we do not accept them not having the a/c or heat for proper temperature, ventilation and comfort. He has rebuilt our A/C for literally pennies on the dollar helping it last and perform beyond its years and when the time came for a new system (before it went out again and before the sweltering summer), we got a super duper A/C unit at a fantastic price. He gave us new, modern, economical options as well as high performance and low maintenance options and walked us through choosing the right system for us. Juan's connections with local suppliers and work force, had our new chosen unit professional installed within a week. He checked on the system a week later to ensure it was functioning as expected and that we were satisfied with its performance. Juan was impressively knowledgeable about our Apple Nest and Amazon Ecobee smart thermostats, how to program them and how they connected to our phones. (Shout out for the Ecobee that I found much easier better for our purposes.) Juan was never hesitant to help when I called many times struggling with the Nest. (I ultimately returned the Nest but it might work great for a lot of other people) Having functioning AC and Heat is vital to our business and Juan is a very reliable piece of that puzzle. Juan is on our speed dial and he never disappoints!! We recommend Degree Heating and Air for hassle-free, respectful, professional, knowledgeable service."

"I had an amazing experience with Attic Shield. From the first phone call to the final walkthrough, the team was incredibly professional, punctual and knowledgeable. They took the time to explain everything clearly, provided a fair and transparent estimate, and delivered exactly what they promised. I was impressed with the crew as they arrived on time, worked efficiently, and left the workplace spotless. They removed the old insulation, sanitized the attic, sealed up air leaks, and installed insulation that made an immediate difference in our home?s comfort and energy bills, especially during these warmer days. You can tell they truly care about the quality of their work and the satisfaction of their customers. I highly recommend this company to anyone looking to improve their home?s insulation. You won?t be disappointed!"

Customers say: True professional

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

Heating and Air Conditioning questions, answered by experts

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
