"These folks are great!  The first couple of years that I had this central AC installed, the main HVAC unit would freeze up and flood the closet and adjacent areas.  
After paying another company for the same repair for three years, I finally ditched them and called Weathershield.  They came out, noticed that I had a bad thermostat, replace that, serviced the unit and I haven't had a problem since then. 
The folks are super polite, arrive on time and have had my AC purring now for over four years now.  Can't say enough.

"Skyline HVAC did an excellent job installing my AC. The installer was professional, on time, and clearly knew what they were doing. They explained the process, worked efficiently, and made sure everything was installed cleanly and correctly. Before leaving, they double-checked that the system was running perfectly. My AC works great and I’m very happy with the service. I’d definitely recommend Skyline HVAC to anyone needing quality HVAC work."

"I cannot say enough good things about Happy Ducts HVAC solutions. I used them a few months back to clean the air ducts in my home and was beyond impressed. Since then I have hired them to do all of my restaurants as well. They are extremely professional, do an immaculate job and have upfront, honest pricing. I had about five other companies bid on my restaurants to clean the air ducts and Happy Ducts was the clear winner when it comes to price, reputation and service. There is no need to look any further. Hire these guys for all of your HVAC needs."

"Fixed my poor ventilation of my dryer duct. Don't know how effective the hvac duct cleaning was. I figured it didn't hurt to do it once since it's never been done but mostly purchased deal for dryer duct."

Heating and Air Conditioning questions, answered by experts

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.

If you’re looking for a portable, budget-friendly cooling solution that doesn’t require any venting or installation, a ventless AC system is a good option. Similarly, this is a great choice if you’re renting an apartment or home and aren’t allowed to make large, structural changes like installing comprehensive HVAC, or you’re in a shared space and only need to cool your own room.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.
