"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

"We were delighted with our generator project. Everyone from Sunrise Comfort Solutions was so genuinely focused on making certain that our selection, installation, and generator operation exceeded our expectations. Covid protocols were practiced. Selection of a properly sized generator is the key to your satisfaction when it's needed. Your sale exec will conduct a thorough evaluation of tour home systems. Installation is a complex process; done with expertise. Testing and homeowner in- service were a cinch. Service does not end with the installation. The contractor followed up to ensure our questions were all answered. Communications were excellent throughout the process. I look forward to working with Sunrise Comfort on future projects at our home."

Install Boiler FAQs, answered by experts

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

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.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

DIY is not recommended due to safety risks and technical expertise required. Hire licensed professionals.

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.
